```
    def test_magic_parameters_cannot_be_used_in_arbitrary_queries(magic_parameters_client):
        response = magic_parameters_client.get(
            ""/data.json?sql=select+:_header_host&_shape=array""
        )
        assert 400 == response.status
>       assert ""You did not supply a value for binding 1."" == response.json[""error""]
E       TypeError: list indices must be integers or slices, not str
```

The test fails because `response.json` here is the empty list `[]`.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",904537568,

Prior to this change we return the following JSON:
```json
{
    ""ok"": false,
    ""error"": ""You did not supply a value for binding 1."",
    ""status"": 500,
    ""title"": null
}
```
But this comes from the `handle_500` higher level code here: https://github.com/simonw/datasette/blob/eae3084b46e2c3931db12cdef79093ad0e644bce/datasette/app.py#L1251-L1263","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",904537568,
